You are using pip v 8.1.1, version 19.0.2 available, try upgrading
pip install  --upgrade pip
shows pip 19.0.2 is in /home/user/.local/lib/python2.7/site-packages

IE it references Pip for Python2.7

""I was facing the same issue on 16.10, upgrade to 17.04 didn't help. I'm pretty sure the problem started because of python3 packages conflict, looking at the trace of the exception it seemed like it was using packages from /usr/lib/python3 (apt managed) and from /usr/local/lib/python3.5 (pip managed). I removed all my pip installed packages, I reinstalled update-manager/python3-aptdaemon/etc but that didn't work... After some additional attempts at removing and purging everything and then reinstalling, it seems that update-manager is working when using synaptic backend and not aptdaemon. So far so good. "

 Abdussamad: Thanks, but i dont think a 64bit AppImage will work on i386 platform
Will look at your script anyway, thanks

DireWolfM14: Cant really uninstall Python 3.5 without breaking a whole load of other stuff

v.Electrum-3.3.4
pip: installed qtpy  in /usr/local/lib/python3.5/dist-packages (1.6.0)
synaptic: python-pyqt5 5.5.1+dfsg-3

Python and python 3 commands invoke
error in line 53  sys.exit(f"Error: {str(e)}.
Try sudo python3 -m pip install [module name]
OK 
"sudo python3 -m pip install pyqt5"
No matching distribution found for pyqt5

Thoughts: Python v3.6 -minimal vs Python 3.5, something is missing or not installed for Python 3.6

Install Python 3.6 from a PPA repository as required by newest Electrum app
Get source code
python3.6 Electrum-3.3.4/run_electrum

crashes
module not found error - 'PyQt5.QtGui'

python3.6.7-1~16.4.york from PPA
launchpad.net/~jonathonf

Anyone have any ideas?
